What do you mean by "column matrix(nxn)"..?
Column matrix is supposed to have only one column, so it should rather be (nx1).
I mean to say column vector of (nxn) form

Difficult to answer with that little detail.. Maybe:
M = reshape( v, n, n ) ;
M = reshape( v, n, [] ) ;
with a transposition ( .' ) afterwards if needed.

During the usage of RESHAPE function i have to mention that how many rows and column matrix we need.But in my case we have to assume n number of column vector which we have to transform in (mxn) . if i use reshape function then it looks like:-
disp('start recording');
disp('stop recording');
double (s);
s= reshape (double(b), m, n);
here in our case we want m and n value by some logic rather look at the column vector value. Suggest me some logic and thanks for your previous suggestion.
I just don't understand what you want to achieve. After you stop recording, variable b is a 40000x1 vector. What do you want to do with it and why? Why a matrix?
